Original job description

👫 About the team
At Equativ, we’re on a mission to develop advertising technologies that empower our customers to reach their digital business goals. This means that we rely on massively scalable, widely distributed, highly available, and efficient software systems; the platform deals with over 3 million requests per second (+250 billion/day) managed by 3,000 servers with less than 250ms response time.

Our innovation team based in Paris, Nantes, Bordeaux, Limoges, Krakow and Berlin is composed of 150+ straightforward and energetic engineers working in an Agile environment and ready to tackle the most complex technical challenges.

Creative Solutions builds the technology behind how ads are created, enhanced, delivered, and experienced. Our work spans creative tools and dynamic enhancements, as well as the systems that render and measure ads across the web and apps. Projects range from shoppable ads and video experiences to high-scale delivery, ad integrations, and tools that help us understand and improve performance.

We work closely with Product, Design, Data, and various Engineering teams. We use AI coding agents in our day-to-day work to explore code, plan, implement, review, and investigate issues. We value sound engineering judgment and take responsibility for the work we ship, whether or not AI helped produce it.

The Mission 👇
As a Senior Software Developer in Creative Solutions, you will help build and operate products and systems that make advertising experiences better. Depending on the team and its priorities, your work could focus on creative enhancements, web rendering and delivery, or the services and tools that support them.

You will help shape solutions from the problem through to production, working with teammates across disciplines and improving the systems and practices we rely on.

What You'll Do ✏️

Work with Product, Design, and other Engineering teams to understand problems, define solutions, and make informed tradeoffs.
Design, build, test, and maintain software across the stack, from user-facing tools and ad experiences to backend services and delivery systems.
Take ownership of projects from investigation and technical design through deployment, monitoring, and iteration.
Investigate production issues across system boundaries, using data and collaboration to understand their impact and fix the underlying problem.
Build reliable, performant software that works at scale, and improve existing architecture and engineering practices along the way.
Use AI coding agents as part of your workflow, review their output critically, and share useful approaches with the team.
Contribute to code reviews, pairing, and technical discussions; mentor teammates and help make the team more effective.

About You 💪

You have senior-level experience building and maintaining production software, with a strong foundation in JavaScript or TypeScript and backend or full-stack development.
You can work through an ambiguous problem: ask questions, identify constraints, make decisions, and move toward a solution.
You care about how software behaves in production, including reliability, performance, testing, and maintainability.
You can work independently while keeping teammates informed, asking for help, and sharing context clearly.
You want to understand the product and business reasons behind your work, not just implement a specification.
You use AI tools in your day-to-day work and exercise your own judgment about when and how to use them. You understand and take responsibility for the code you ship.
You're comfortable learning new technologies and working in unfamiliar parts of a system.

Nice to have 🌟

Experience with Node.js, React, NestJS, Nx, Docker, SQL, or cloud platforms such as GCP.
Experience with browser technologies, ad rendering, video, ad tech, or high-throughput distributed systems.
Experience building with LLMs, whether an agent, an internal tool, an evaluation, or a product feature.
Examples of improving how you or your team work, such as automating a recurring task or building a useful tool.
Experience leading technical initiatives, mentoring teammates, or improving team practices.
